Spine playrate not correct on Windows (DEF-2887)

[britzl]

Description: From forums: [(LINK REMOVED){quote}We have lots of Spine animations with flipbook-animations in the timeline. (one key of changed image per frame) This works smoothly on OSX and iOS. But not so much on Windows. The whole game is running on 60 fps with no stutter but the spine animation is barely looking like 20-30 fps stuttering in its animation. The animation itself takes the same amount of time to play, its just as if it skips every second frame. {quote}

Steps to reproduce: Run the "Test_project_2" project (id: 71576, ask [~sven.andersson] for access) on a Windows machine.

Expected result: Should behave the same as on any other platform.

Actual result: According to report, seems to be skipping frames. (Unverified, need verify on our machines.) 2017-10-11 15:03:32 (sven.andersson) Could not reproduce! Andreas from Strangequest will be here on Monday (16/10), will try to recreate on his hardware.

I'm thinking this is due to the general vsync issues we've had. Might be fixed in Defold 1.3.1
